SENSE OF TASTE

The receptors for taste, called taste buds, are situated chiefly in the tongue, but they are also located in the roof of the mouth and near the pharynx. They are able to detect four basic tastes: salty, sweet, bitter, and sour. The tongue also can detect a sensation called "umami" from taste receptors sensitive to amino acids. Generally, the taste buds close to the tip of the tongue are sensitive to sweet tastes, whereas those in the back of the tongue are sensitive to bitter tastes. The taste buds on top and on the side of the tongue are sensitive to salty and sour tastes. At the base of each taste bud there is a nerve that sends the sensations to the brain. The sense of taste functions in coordination with the sense of smell.

 Answer these questions:
1.why is sense of taste important?
2.what is the use of sense of taste?

Healthy and Unhealthy Environment

A child's environment plays an important part in his/her growth and development.


Observe the surrounding:

Answer these questions:

1. What can you say about the streets?

2. Can you tell the kind of place this is?

3. Why is this desirable place to live in? 

Observe this next picture:

Answer these questions:

1. What can you say about the surroundings in the picture?

2. What effect does a dirty surrounding have on the health of a people living there?

3. Compare this picture with the other picture above. Which surrounding is better to live in?Why

 Water Pollution

Water pollution happens when chemicals, wastes and other harmful organisms are added to the water. this water becomes dirty and is harmful to public health


Activity:


Describe how water is polluted in each picture. Tell how this pictures can be prevented.

Addition and Subtraction

Addition and subtraction concepts have been developed through hands-on experiences with countable objects or place value blocks. Addition is the "putting together" of two groups of objects and finding how many in all. Subtraction tells "how many are left" or "how many more or less."
We say addition and subtraction are inverse operations because one operation can "undo" the other operation. Adding 3 and 5 to get 8 is the opposite of 8 minus 5, leaving 3.

3	+	5	=	8	and	8	–	5	=	3
addends				sum			difference

(SCIENCE AND HEALTH 3) The Parts of a Flower

Peduncle: The stalk of a flower. Receptacle: The part of a flower stalk where the parts of the flower are attached. Sepal: The outer parts of the flower (often green and leaf-like) that enclose a developing bud. Petal: The parts of a flower that are often conspicuously colored. Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. Stigma: The part of the pistil where pollen germinates. Ovary: The enlarged basal portion of the pistil where ovules are produced. "Answer these questions:" 1. why does the parts of the flower important? 2. are the parts of the flower are important for its reproduction?                                                                                                            --Regine Fernandez
